why can’t I accumulate coins? – Rocket Mania Frenzy Review

I thought I had to buy the premium version to collect and accumulate coins, but I still can’t. Half the time the game doesn’t seem to know that I paid for it. I’m disappointed because I love this game, but when I can’t upgrade my rockets I can only get so far ?
